This study aimed to retrospectively analyze the early outcomes of bicuspid aortic valve (BAV) neocuspidization for Type 0 bicuspid aortic annulus. Bicuspid neo leaflets were created and surgically sutured using Ozaki's neocuspidization technique with indigenously developed valve templates. The study was conducted at the Department of Cardiothoracic and Vascular Surgery, GB Pant Postgraduate Institute of Medical Education and Research, New Delhi, for the patients operated between June 2022 and March 2024. Bicuspid neocuspidization was performed in patients with BAVs who required aortic valve replacement and were not candidates for tricuspid neocuspidization. A total of 8 patients were found to have Type 0 BAVs during the study period. In one of these patients, tricuspid neocuspidization was done, while in the remaining 7 patients, bicuspid neocuspidization was done. In 1 patient of bicuspid neocuspidization, concomitant root replacement was done and was excluded. The outcomes of 6 patients are hereby presented. There was no mortality. The mean postoperative gradient was 14.5 (+ / - 0.9) mm Hg. There was trivial aortic regurgitation in 2 cases of bicuspid neo valves while 4 cases of bicuspid neo valves had no neo aortic valve regurgitation. The average coaptation length of the neo valve was 14.8 (+ / - 0.5) mm.
